One centre reported the dispersion of effluents caused by a leak in the wastewater drainage pipe from the toilets of the ITR rooms onto the public thoroughfare situated below the rooms, within the grounds of the centre. Work has been carried out to replace sections of the wastewater drainage network. • …Ɏǝƺȸ ƺɮƺȇɎɀ ٢ ژג 0³«ɀً ǣِƺِ ۏא Ȓǔ Ɏǝƺ ȸƺȵȒȸɎƺƳ 0³«ɀ٣ The other events concerned, for example, the loss of medical staff dosimetric data due to a computer failure. SUMMARY The radiation protection of patients and professionals in nuclear medicine is dealt with satisfactorily. The training efforts must also be maintained in this sector. In addition, the coordination of preventive measures during work by outside contractors (for equipment maintenance, cleaning of the premises, etc.) must be improved. One of the radiation protection challenges is also to ensure good management of radioactive effluents, which is all the more important given that therapies administering high activities to patients are going to increase in number, leading to an increase in the discharged radioactivity. 218 ASN Report on the state of nuclear safety and radiation protection in France in 2019 ׎ ٲ ו MEDICAL USES OF IONISING RADIATION
